APPARATUS FOR COOLING CANDY-STICKS.

Specification of Letters Patent.

Application filed November 1, 1909.

To all whom it may concern:

Be it known that we, PAUL R. CAMP and THOMAS J. EUBANKS, citizens of the United States, residing at Marietta, in the county of Cobb and State of Georgia, have invented new and useful Improvements in Apparatus for Cooling Candy-Sticks, of which the following is a specification.

This invention relates to the manufacture of candy, and more particularly to the production of candy sticks; and it contemplates the provision of a compact and efficient apparatus for cooling candy sticks so as to render the same fit for boxing.

The invention also contemplates the provision of an apparatus for the purpose stated constructed with a view of rendering it unnecessary for an attendant to pay any attention to the apparatus except to take the cooled candy sticks therefrom at intervals as will be hereinafter set forth.

With the foregoing in View the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a side elevation of an apparatus constructed in accordance with our invention and constituting the best practical embodiment of the invention that we have as yet devised. Fig. 2 is an end elevation of the apparatus. Fig. 3 is a side elevation of one of the trays comprised in the apparatus. Fig. 4 is a side elevation, and Fig. 5 a horizontal section of one of the cam-actuated levers of the apparatus. Figs. 6, 7, 8, 9, 10 and 11, are views of working parts of the apparatus hereinafter referred to in detail. Fig. 12 is a detail transverse section taken in the plane indicated by the line 12-12 of Fig. 1 and showing the arrangement of the support N in the guides N that are connected to the main frame and braced by the bars N Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is the main frame of the apparatus, which is of the general configuration shown in Figs. 1 and 2. The said main frame is provided at its opposite ends and at opposite sides of its longitudinal center with upright guideways afor the end portions of trays hereinafter described. The guideways a are open at their upper and lower ends, and the upper ends of the guideways at one side of the apparatus are connected with the upper ends of the guideways at the opposite side by a horizontal support I), Fig. 2; the invention contemplating raising the superposed trays step by step at one side of the apparatus, moving the trays across on the sup port 6, and lowering the superposed trays at the opposite side of the apparatus.

For the purpose of moving the trays horizontally at the top of the apparatus, as stated, we provide the follower B having upwardly extending apertured lugs 0, Figs. 1 and 2. The said lugsc receive rods 42? through the medium of which the follower is moved in opposite directions, and each rod d is provided at one side of the adjacent lug with a nut e, and at the opposite side of the lug with a coiled spring f interposed between the lug and a second nut on the rod. Thus it will be manifest that when the rods d are pulled toward the left in Fig. 2 the action of said rods on the follower will be cushioned and the follower will be drawn in the same direction. It will also be manifest that when the rods (Z are moved toward the right in Fig. 2, the nuts 6 acting against the lugs a will move the follower B toward the right. The movement of the follower B is from the posit-ion shown by dotted lines in Fig. 2 to a position at the right hand side of the right hand series of superposed trays and return, and from this it follows that the follower is adapted to move the tray into the position shown by dotted lines in Fig. 2 above the support I), and then upon its succeeding movement toward the left, is adapted through the medium of the tray before it, to move the first mentioned tray from the position above the support I) to a position at the top of the series in the left-hand guideways a of the apparatus.

0 is the drive-shaft of the apparatus. The said drive-shaft is equipped with a band pulley it, and from the shaft the follower B is moved to and fro through the medium of the following driving connection, viz: a spur gear 2' on shaft C, a spur gear j intermeshed with the said gear 2' and fixed on a shaft D, disks E (one of which is shown in Fig. 9) fixed on the shaft D and having cam grooves 71: in their outer sides, suitably supported levers F and G having lateral projections Z disposed in the grooves 7c of disks E, an

: arm H fixed to the adjacent lever G, arockshaft I journaled in suitable standards we at the top offthe main frame A and having cranks a connected to the rods d, and also having an end crank p, and a rod J extending between and connected to the arm H and 39.- By virtue of the construction described,

oscillation of the "lever G by the cam disk E adjacent thereto, will be attended by os-. cillation of the arm H, and consequently the r follower B will be moved in the manner ,ibefore described at the pro-pertimes. It

:will alsobenoted at this point that because Of the confi uration of the cam groovesla in .the disks'ln, ithe levers F and G and the farm'Hwill have periods of idleness, as will also'thefollower B; the periods of idleness of the said follower B occurring. while the fol-" loweris at the right-'handside of the right hand vertical series o-f'trays. i

JiL'L are the trays of the apparatus of which sixty two are employed. The said trays are identical in construction and therefore a detailed description of the one shown in'Fig. v3wvill suffice to impart a definite understa'ndingof all. a The said tray L, Fig. 3, comprises a' rectangular metallic plate 9" .offgreater' length than width, transverse strips of'woo'd fixed tothe'under side of the .plate and arranged about the distance illustrated from the ends thereof, and a plurality of upstanding transverse partitions I t fixed on the upper side of the plate and designedto receive between them and to hold apart the candy sticks or sections to be cooled. .We prefer to employ the said 7 partitions t for the purpose stated, but we do not desire to be. understood as limiting ourselves to the use thereof, inasmuch as fbelow the left-hand vertical series of trays in'Fig. 2, to a position below the right-hand vertical series of trays N' is a' longitudinally movable, horizontal support which is preferably in the form of fa metallic plate, as shownin Figs. 1, 2, .8, and12, The said support N is arranged in a horizontal plane slightly above the plane .ofthe'supports'M, and is reciprocated by thedrive-shaft 0 through the spur gear 1', the spur gearj, the shaftD,a miter gear P "on the shaft D, a miter gear Q, fixed on a suitably supported shaft R disposed atright angles to the shaft 1), and intermeshed with frame. D 1s a'roller having trunnion's a ourthe shaft a horizontal shaft Z a miter around the roller D the miter gear P, a "cam S fixed on the shaft R and having a' heart-shaped groove T, a lever U having a lateral projection V disposed in the said cam groove, a lever W mounted at about the distance shown from the main frame A, a link X connecting the levers U and W, and a link Y connecting the lever 'VV and the outer end of the support N, all as clearly shown in Fig. 1.

Z Z are brackets extending from one end of the main frame A. A is a shaft journaled in said brackets and bearing sprocket wheels B C ,Fig. 1, is oneof a pairof brackets extending from the opposite end of the main naled in movable bearings, 41 mounted in the brackets C and E is an endlessconveyer mounted on the sprocket wheels B and the roller D and having spaced cross-bars w; the spaces between the said cross-bars w being designed to receive candy sticks or sections that are to be cooled. The said conveyer E is driven from thedrive-shaft C through the medium of the spur gear i on the said shaft 0, the spur gear j on the shaft D, asecond spur gear a? on shaft D, a suitably supported spur gear 6 intermeshed with the spurgear a a spur gear c fixed on a shaft d and intermeshed with the spur gear N, a miter gear 0 also fixed on the shaft 03 a miter gear f fixed on a shaft 9 disposed at right angles to the shaft d and intermeshed with the miter gear 6 a miter gear it fixed on the shaft g ,a vertical shaft a miter gear 7' on the lower end of said shaft intermeshed with the miter gear If, a m ter gear 70 on the upper end of gear m fixed on said shaft and intermeshed 'with the miter gear 76 a miter gear 11. on the other end of the shaft Z and a miter gear 79 fixed on the shaft A and intermeshed with the said miter gear M.

We would here have it understood that the candy sticks to be cooled are supplied one by one to the upper stretch of the conveyer E at about the point No. 1, and that disposed below the upper stretch ofthe conveyer is a fixed support F which has for its oflice to prevent the candy sticks from dropping from the upper stretch of the conveyer. Said support F also serves, during the movement of the conveyer in the direction indicated by arrow, to straighten any candy sticks that maybe bent at the time the same are placed in the spaces between the crossbars w of the conveyer. The support F extends to a point adjacent the roller'D and a guard or shield G curved as shown, is employed to prevent the candy sticks from dropping from the spaces in the conveyer E while the said spaces are passing The before described support N is moved longitudinally inward at a rate of speed corresponding to that of the conveyer E so as to enable the said support N to support the candy sticks as soon as the latter pass beyond the lower edge of the guard G and when the said support N reaches the end of its inward traverse it is withdrawn or moved back to the position shown in Fig. 1.

Our invention contemplates the disposition of one of the trays L on the supports M and below the lower stretch of the conveyer E at the time that the support N is moved outward as described, and from this it follows that the candy sticks released from the conveyer by the outward movement of the support N will drop one by one into the spaces between the partitions t of the mentioned tray.

From the position below the conveyer E the tray mentioned is moved to a position below the guideways a at the right of Fig. 2, and is then moved stepby step up the said guideways a, then across on the upper horizontal support 6 to the upper ends of the guideways a at the left of Fig. 2, then step by step down through the latter guideways a, and then back to the position below the lower stretch of the conveyer E and this course of movement is common to all of the trays employed.

It will also be understood from the following detailed description that the described movements of each tray are effected in part by the tray or trays behind it. The described movements of trays carrying candy sticks from a point below the lower stretch of the conveyer E up the right-- hand side of the apparatus and then across and down the other side of the aparatus result in the candy sticks being quite cool when the trays carrying the same reach the lower ends of the guideways a at the left of Fig. 2. We therefore provide a longitudinally disposed fixed brush H for sweeping the candy sticks from each tray incidental to the movement of the said tray from a point below the lower ends of the guideways at the left of Fig. 2, to a point below the conveyer E the relative arrangement of the said brush H being clearly shown in Figs. 1 and 2.

The candy sticks removed as stated from a tray while the same is being moved to the position below the conveyer E are received on the upper stretch of a belt I preferably of canvas, which belt I is driven in the direction indicated by arrow in Fig. 2 by the before-described shaft 2' through the medium of a miter gear a thereon, a shaft a having a miter gear a intermeshed with the miter gear a and also having another miter gear (1, and a roller 0 having a miter gear a intermeshed with the miter gear a. The roller a supports the outer portion of the belt I and said belt is also supported by a roller 0;, and an idler roller a, the latter being designed to prevent the lower stretch of the belt from interfering with the movement of certain parts hereinafter described.

The cooled candy slicks deposited on the belt I are carried by the said belt to a point at the left-hand side of the main frame in Fig. 2, and are removed from the belt at such point by hand or otherwise, and are then fit to be packed in boxes.

As will be observed by reference to Fig. 2, the upper stretch of the belt I is disposed in a horizontal plane above the fixed horizontal supports M, and from this it follows that while, during the movement of each tray from a position below the lefthand vertical series of trays to a position below the conveyer E the plate 1" of the tray will rest above the upper stretch of the belt, the strips .9 of the tray will rest and move on the supports M.

Disposed under the upper stretch of the belt 1 and movable on the supports M in position to engage the outer ends of the strips 8 of a tray resting on the said supports, is a follower M which is connected through bars 1 4 with the upper ends of the before described levers G. Thus it will be seen that when the said levers G are moved toward the right in Fig. 2, the follower M will move before it and to a position below the conveyer, a tray lowered from the guideways a at the left of Fig. 2; also, that upon the movement of the levers G in the opposite direction, the follower ll 3 will be returned to the position shown in Fig. 2. It will further be noted in this connection that the described movements of the follower M will be coincident with the movements of the follower B at the top of the apparatus, and that the movements of both followers will take place while the two vertical series of trays are at rest.

P P are cams fixed on the shaft D.

Q Q are suitably supported levers fulcrumed at their outer ends and having antifriction rollers R R at points intermediate their ends for the engagement of said cams.

S S are rods connected to and reaching upward from the inner ends of the levers Q and T T are levers fulcrumed at intermediate points of their length and connected at their inner ends with the rods S There are two or a pair of the levers T adjacent each end of the apparatus, and the outer ends of the said levers are arranged under tray elevators U Figs. 1, 2, 10 and 11, there being two of the said elevators employed, and one being disposed at one side of the longitudinal center of the apparatus, and the other at the opposite side of said center.

As will be readily observed by comparison of Figs. 10 and 11, each elevator U com- 'pris es a longitudinal bar a (shown as broken in Fig. 10), stems b fixed to and extending above and below the ends of the longitudinal bar, and T-heads c fixed on the'upper ends of the said stems. The stems 5 10f the elevators are suitably guided and V movable vertically in the main frame A, and the bars a are arranged above and in engagement with the outer arms of the levers T "The T-heads cfof the elevators are arranged in the same vertical planes as the strips 8 of thetrays L, and when the elevators are; in their lowermost positions the saidi cT-heads 0 rest in recesses '01, Fig. 2, inthe supports M and below the upper sides ofthe said supports. By'virtue of the described construction and relative arrangement of the tray elevators Uiflit will be manifest that when the innerarms of the e on an enlarged scale in- Figs. 6 and 7 and by reference to said'figures it will be noted that the latch is in the form of a lever that 'is' fulcrumed' at an intermediate point of its length on a support W and has an upper arm adapted to assume a posit-ion below the extended end portion of each tray, and

a lower arm between which and the main 7 frame a coiled s ring X vis-supported and interposed, the o cc of the said springbeing to return the latch to andfyieldingly hold the same in the position shown in Fig. 7

Fixed to and extending outward from the tray elevator U at the left-hand side of the apparatus are two tappets Y designed on upward movement of the elevator to .en-

' gage and press the lower arms of the latches V adjacent said tappets inward against the action of the springs X complementary to the said latches. Y e

The operation having to do with the transfer of the trays to and from the vertical guideways a is as follows: A. tray being in place under the guideways a at the right of Fig. 2, the elevator U at that side of the apparatus will on its upward movement raisethes'aid tray and move the same past the upper arms of the adjacent latches V whereupon the said tray. will raise the superposed trays above'it and will itself as sume a position abovethe upper arms of the latches, whereupon it and the other trays in the vertical series will be supported by the latches. At the same time the elevator U 'at the left-hand side oflthe ap paratusin Fig.2 engages and slightly raises the lowermost tray in the left-hand vertical series as well as the trays above said lowermost tray, and then the tappets Y on the left-hand elevator engages the left-hand latches V and releases the said lowermost tray and allows the same to descend to the supports'M, the upper arms of the said latches V in the meantime resuming their normal positions so as to engage and support the next upper tray of the series and'the superposed trays above said tray. The tray lowered by the left-hand elevator U is then moved by the follower M toward the right in Fig. 2 and to a position below the endless conveyer E and while the said tray is en route to said position the brush 2 sweeps the cooled candy sticks from the tray and causes said sticks to assume positions on the upper stretch of the endless belt I by which the sticks are carried to a point at the left-hand side of the apparatus in Fig. 2 from whence they 'may be removed by hand or in any other manner consonant with the purpose of our invention. Thev tray moved as stated under the conveyer E is supplied with candy sticks from the conveyer in the manner before described, and then upon the succeeding movement of the follower M toward'the right in Fig; 2, the'said follower through the medium of the full tray placed before it, serves to move the first-named tray from the position below the conveyer E to a position below the right-hand guideways a, and this operation is continued during the working ofthe apparatus;v the trays being carried in a closed cycle up one side and across the top and down the other side and across the bottom of the apparatus, and being charged with and discharged of the candy sticks in the manner described in detail.

It will be gathered from the foregoing that our novel apparatus is possessed of large capacity, and thisnotwithstanding the compactness of the apparatus, and the fact that it takes up but a small amount of floor space. 7
